Application that crashed: plasma-desktop
Version of the application: 0.3
KDE Version: 4.3.2 (KDE 4.3.2)
Qt Version: 4.5.2
Operating System: Linux 2.6.31-14-generic x86_64
Distribution: Ubuntu 9.10

What I was doing when the application crashed:
plasma-desktop crashes on startup, everytime. Still crashes when I restart the application.

I think it's due to one of the addons as I experienced that the plasma-desktop crashed earlier while adding a plasmoid.

If I rename the .kde folder in home, plasma-desktop works fine again.
